When we experience a cut or wound, white blood cells rush to the area to prevent infection. A team of researchers has discovered the initial step in the healing process. A flash of calcium is the initial signal that sets in motion a sequence of events that attract white blood cells to an injured area. White blood cells destroy bacteria and other microbes in the injured area.
According to researcher Will Razzell, "We are more than ever understanding the pathways that lead to immune cell attraction to wounds. As calcium represents the immediate inflammatory signal, we now have a good foundation to investigate this complicated process further." The researchers contend that learning how immune cells are regulated at wound sites will aid in the development of future treatments for wound injuries.
